The rifle came with rcbs dies and 40 pieces of Norma brass. I wanted more brass so I picked up a box of 50 Hornady 7mm mag brass. I wanted to see if I could make 7x61 from 7mm rem mag just using the sizing die. Even with the die down on the shell holder it was not pushing the 7mm mag shoulder back far enough to chamber. I removed a bit of material from the bottom of the sizing die and it then worked perfectly. I adjusted the die down a little at a time until a trimmed case would just chamber in the rifle. I did all 50 pieces of Hornady brass without losing any. I then annealed them and they are ready to go. I don't know how their case capacity compares with original 7x61 super brass. I plan to try it out tomorrow.
That's the way! However, depending on the sizing dies, you could run into trouble. If so. You use the seating die first, then the size die, forming should be easier yet, with no crushed case failures.
We use this method in a bunch of different wildcat ctgs.
